“…Tree abundance signi�cantly predicted liana abundance in the study. is �nding provides support for other studies which reported of signi�cant dependence of liana abundance on abundance of trees [15,40]. e absence of signi�cant relationship between liana abundance and canopy cover may be related to the ability of liana species in the forest to regenerate and grow well in shade and canopy gaps [39], leading to no clear cut pattern.…”

“…For instance, in the Bobiri Forest Reserve, Ghana, a total of 27 species (≈18 species/ha) was recorded [17] whereas a much lower species richness (27 species ≈ 9 species/ha) was reported in the Tinte Bepo Forest Reserve, Ghana [15]. Moreover, liana species richness in this study was higher than those reported from outside Ghana: 51 species/ha in Bolivia [28] and 44 species/ha in China [29].…”

“…In the present study, liana density of 406 individuals/ha obtained was higher than what was reported in the Tinte Bepo and Bobiri forest reserves (253 individuals/ha and 213 individuals/ha, resp.) [15,17]. In the Democratic Republic of Congo, liana densities of 54 and 239 individuals/ha were recorded in a monodominant and mixed stands, respectively, in Ituri Forest [30].…”

“…Human disturbance has been identi�ed as one of the main drivers of liana success in tropical forest ecosystems [3,4,11,15,16]. Both patterns of increasing and decreasing liana diversity and structure have been reported in tropical forests, although majority of them have centered on the former [17].…”

e study was conducted to determine the factors that in�uenced liana species richness and structure in forests of different disturbance intensities (high, moderate, and low disturbance forests) in the Southern Scarp Forest Reserve, Ghana. Within each forest, lianas (dbh ≥ 2 cm) were enumerated in six 25 × 20 m 2 plots located along transects. Soil physicochemical properties and forest structure were determined within the plots. Liana species richness and abundance were signi�cantly lower in the high disturbance forest ( 0 00 ) whereas basal area was signi�cantly higher in the low disturbance forest ( 0 0 ). Tree abundance and dbh signi�cantly predicted liana species richness and structure in the study ( 0 05). On the basis of the importance value index, three main liana communities, each corresponding with a forest type, were identi�ed. Stepwise multiple regression analysis revealed that exchangeable magnesium and calcium, and total exchangeable bases were the main soil variables that affected liana species richness. Liana structure was in�uenced by the above-mentioned soil variables as well as exchangeable potassium and sodium, and pH. e present study has demonstrated that changes in liana species richness and structure following human disturbance may be due to variations in soil properties and forest structure.

“…Lianas could, for instance, suppress natural regeneration of trees when they become highly abundant . Consequently, lianas are usually cut in managed forests as a form of a silvicultural treatment (Pérez-Salicrup 2001; Alvira et al 2004;Addo-Fordjour et al 2009a).…”

This study analysed the impact of the Malayan Uniform management System (MUS) on liana abundance and their relationship with trees in the Bukit Panchor Forest Reserve, Malaysia. Two types of MUS-treated forest, medium-term MUS (M-MUS) and long-term MUS (L-MUS), were identified based on the management time span (19 and 42 years, respectively). Trees with diameter at breast height ≥ 10 cm were identified and examined for liana presence (diameter ≥ 2 cm) in ten 40 m × 40 m plots within each forest. Tree seedling and sapling abundance were also determined in a randomly selected 20 m × 20 m subplot within each plot. Liana abundance and infestation rates were significantly higher in the untreated forest than under the M-MUS, although they did not differ from those under the L-MUS. Tree diameter related significantly with liana load and basal area in all the forests except the M-MUS, which contained relatively more uniform diameter trees. Reduction in liana abundance and infestation in the treated forests favoured natural regeneration of the trees. Liana cutting was effective in reducing liana abundance and infestation in the medium term but not in the long term. Therefore, further liana cutting in the long term may be needed to control lianas.
